Sizes run small. I love this coat though. Actually bought it for my mom. And she told me she loved it. But it was a little tight. So I tried it and I loved it. So I kept hers. I am usually a size Medium. The size large I bought for my mom, fit me perfectly. I bought an extra large for her, and it's her favorite thing ever. She is sad it's getting warm out and she only got to wear it a few times.
